The IX Iberian Cosmology Meeting took place in Aveiro, Portugal, at the Physics Department of the University of Aveiro, from the 28th to the 30th of April 2014. This series of meetings is aimed at encouraging the interaction and collaboration between researchers working in Cosmology and related areas (Gravitation, Particle Physics and Astronomy) in Portugal and Spain. Researchers working in other countries will also be most welcome.
Curvature perturbation in multi-field inflation models with non-minimal coupling

Abstract: Recent observations of the Cosmic Microwave Background (CMB) show very good consistency with an inflationary model with non-minimal coupling between the scalar and the inflaton field. Such a model is well motivated in the context of the unified theory, which also predicts the existence of many other scalar fields in addition to the inflaton.

Abstract: Three-forms can give rise to viable cosmological scenarios of inflation and dark energy with potentially observable signatures distinct from standard single scalar field models. When applied to inflation, a three-form can provide a scale invariant scalar perturbations power spectrum and I will discuss the effect on primordial non-gaussianity. Finally I will discuss a

Abstract: We discuss the main features of a phase-space noncommutative model of quantum mechanics and its applications for quantum cosmology and black holes in the context of the Kantowski-Sachs minisuperspace geometry.
Introduction to Cosmology

This is an introductory course in Cosmology, aimed primarily at Masters and PhD students but open to anyone who would like to know more about the Universe. It will focus mainly on describing the Hot Big Bang paradigm, its mathematical properties and the observational basis on which it stands. The course will be mostly self-contained but some parts of the course will require a basic knowledge of general relativity, quantum field theory and thermodynamics, although the main concepts will be revised.
